I need a little help on 2 issues

I am trying to code a small custom music player, my first issue is specifying the music file to be played.

I am trying to specify a specific file in my Music folder, but using this gives me a “Error 701: Unable to load file”. What am I doing wrong?

Secondly, I want to be able to choose a music file at random from the entire /Music folder, I have not been able to figure out how to do that, any help?


Update: I figured out the proper syntax; “/storage/emulated/0/Music/Welcome To My World.mp3”, however, now I am getting a permissions error;

“Error 908: The permission READ_EXTERNAL_STORAGE has been denied. Please enable it in the settings app.”

so, I tried adding this;

Which didn’t seem to have any effect at all.

Try this:

I think you are misunderstanding; the app never asks me for permission.

If you have used this block:

you will definitely be asked for permission.
Of course, I talking about the compiled app (APK).

I can quite gaurantee you, it does NOT ask permission.

I just checked it. You are correct, the READ permission is no longer added to the Manifest.
It’s a bug. @ewpatton

As a workaround add the File component (as a dummy) into your project. This component adds both permissions to the Manifest (READ-/WRITE_EXTERNAL_STORAGE).

NOTE: To be able to ask for permissions, they must be declared in the Manifest.

Thank you!

Now I just need to figure out how to select a file at random…

@Michael_Cole @Anke Thanks for the investigation into this issue. I’ve prepared a patch that will fix this issue in future releases:




Hello, I am running into the same problem as well. Could you please tell me what specifically you added to your project to make it work? what does adding a dummy file component mean?

Hello, I am running into the same problem as well. Could you please tell me what does adding a dummy file component mean? I don't understand immediately what I should do.

So drag the File component onto the screen in the Designer.
That's all.


Hello, Thank you so much for the reply. However, the app is still giving me the same permission denied error. I assume I would have to declare it in the manifest, but I don't understand what that means as well. Could you please explain what specifically I should do for that part? Thank you so much for the help.

Set the DefaultFileScope to Legacy in the Designer.

Please note that you should change the Screen's DefaultFileScope property, not the File's.


It Worked!!! Thank you so much.

Seems like I hit this bug as well. The app is working fine on the Android 8 phone but not on the new 14. It gives error "Permission missing. READ_EXTERNAL_STORAGE is required. Bye.". I tried to use advice given by @Anke but seems that there is no such option in the Designer any more.

On Android 13+ there is no longer READ_EXTERNAL_STORAGE permission. You must request "READ_MEDIA_IMAGES" (and/or _AUDIO, _VIDEO) on Android 13+. As soon as it is requested via blocks, it is also declared in the Manifest.
